Fundamental Period for Steel Frames Calculator

Fundamental Period - (Measured in Second) - Fundamental Period is the time taken for one complete oscillation (back-and-forth) by the building.
Height of Building - (Measured in Meter) - The Height of Building is the height above the basic to the highest level of the building.

STEP 1: Convert Input(s) to Base Unit

Height of Building: 32 Foot --> 9.75360000003901 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T = 0.035*h_n^(3/4) --> 0.035*9.75360000003901^(3/4)

Evaluating ... ...

T = 0.193170920842961

STEP 3: Convert Result to Output's Unit

0.193170920842961 Second --> No Conversion Required

FINAL ANSWER

0.193170920842961 ≈ 0.193171 Second <-- Fundamental Period
